A Morse keyboard, with a new memory expansion board based on IDT7201 dual-port FIFO memory chip, so you can now type up to 512 characters without having to wait for the transmission to finish.
The 4 LEDs at the bottom show the amount of free memory left and another set of 2 red LEDs shows when a data is read or written to/from the memory.
